SUNNYVALE, Calif.--(BUSINESS WIRE)--May 21, 2001

LuxN, Inc., a provider of multi-service, intelligent, metropolitan optical access network platforms, today announced the LuxN Optical Service Level Management System (OSLM). LuxN OSLM enables service providers to deploy and manage services cost-effectively while maintaining a high level of reliability. The LuxN OSLM will be demonstrated at SuperComm 2001 in booth No. 450D, June 5-7th, with general availability expected in September of 2001.

Currently, service providers have limited or no tools to maintain and manage service level agreements for dense wavelength division multiplexing (DWDM) services to end- customers. With real-time, in-service-Bit Error Rate (BER) monitoring through LuxN's proprietary ColorSIM technology and a comprehensive Graphical User Interface, service providers will be able to create and manage individualized, protocol-independent Service Level Agreements (SLAs) at the physical layer. A wavelength-specific, user-settable threshold allows service providers to offer different SLAs per customer, sub-network, service, link, or wavelength. Service providers will be able to use this tool to generate advance warnings of potential SLA violations, allowing operators sufficient time to arrest further degradation of service.

LuxN OSLM architecture and highly sophisticated integration capability with other operations support systems (OSS), in conjunction with LuxN equipment, enable service providers to offer DWDM services at competitive price points in the access and metro- access markets. Offering real-time monitoring, remote point and click provisioning and upgradability of bandwidth through LuxN's proprietary ColorValve technology, the LuxN OSLM provides a unique capability to deploy and manage services over DWDM.

"The LuxN OSLM technology is unique in the industry and enables us to provide unique services to our customers," said Dr. Kamran Sistanizadeh, chief technology officer of Yipes Communications. "With the ability to monitor and predict any degradation of service, Yipes is secure in its network reliability. We are impressed with the quality of service the LuxN OSLM provides and we look forward to future products developed by LuxN."

"Cost-effective operation with the highest level of service reliability is the developmental cornerstone of the LuxN OSLM. It enables service providers to create and proactively maintain SLAs, manage remote network elements without an extensive IP infrastructure, and troubleshoot and isolate problems quickly and effectively, all the while reducing the total cost of ownership," said Ikhlas Ahmed, senior product manager at LuxN, Inc. "LuxN's highly developed standard-based OSLM can integrate with any OSS employing OSS-specific adapters."
